Stages of Aerobic Respiration

Simple, no diagrams just text i'm afraid :/

just a quick little reminder.

Cos i have a test tomorrow (x

Glycolysis
Glucose (6C)
Phosphorylated with the phosphate from 2atp to activate it
= 1 x hexose biphosphate (6C)
Then it's split to 2 x triose phosphate ( 2 x 3C )
It is oxidised losing hydrogen to make 2 x pyruvate (2 x 3C)
2 NAD take the 2 hydrogen ions forming 2 reduced NAD
Glycolysis makes 4 ATP, but there Is a net gain of 2 ATP
Link Reaction
Pyruvate is decarboxylated (One C removed in form of CO2)
It is then dehydrogenated, NAD collects the hydrogen
Acetate + CoA Acetyl CoA
No ATP
THIS HAPPENS TWICE COS THERE ARE TWO PYRUVATES
Krebs Cycle
Acetyl CoA (2C) + Oxaloacetate (4C) Citrate (6C)
CoA goes back to link reaction to be used again
Citrate is decarboxylated so CO2 is released, making a 5C molecule
It is then dehydrogenated, and reduced NAD is formed from NAD
5C 4C

Here's a taster:

Decarboxylation & Dehydrogenation
1 x reduced FAD
2 x reduced NAD
ATP made from direct transfer of phosphate from an intermediate compound to ADP. Substrate level
